VULCANIZING APPARATUS.

Application filed August 25, 1910. Serial No. 578,883.'

To all whom it may concern:

Be it known that I, JOHN EDWARD HITCH, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Vulcanizing Apparatus,of which the following is a specification.

My invention relates to improvements in portable vulcanizing apparatus.

One of its objects is to provide vulcanizing apparatus self containedand portable in nature, and adapted to be readily and quickly appliedwherever required.

Another objectis to provide apparatus adapted to quickly generate thedegree of heat required.

Another object is to provide means to conveniently, accurately anduniformly maintain the degree of heat required for the purpose.

Another object is to provide means to indicate the degree of heatattained and any change in the degree of heat to enable the desireddegree of heat for the pur ose to be secured and uniformly maintaine Itfurther consists in certain details of form, combination andarrangement, all of which will be more-fully described in connectionwith the accompanying drawings in which;

Figure 1 is a front elevation of my improved apparatus With the burnerin place and drafts partly open. Fig. 2 is a central vertical sectionthrough the same on line o o of Fig. 1. Fig. 3 is a central verticalsection through one of the burner caps; Fig. 4 is a perspective view ofthe burner draft regulating slide. Fig. 5 is a top plan view of myimproved apparatus in one position for use. Fig. 6 is a front elevationof a portion of the vulcanizer with the burner detached. Fig. 7 is aside'elevation of the burner with caps on or closed ready fortransportation or storage. Fig. '8 is a central vertical section throughthe body of the burner detached.

y improved vulcanizer comprises preferably a steam generator chamber, asteam pressure gage, a burner adapted to consume holding the fluepreferably a liquid fuel, a flue directing the eated burner into contactwith the steam generating chamber, and means to protect the flame of theburner from excessive air currents, and to control the air supply to theburner so as to uniformly maintain the desired products of combustionfrom the Specification of Letters Patent.

pressure and temperature in the steam generator until the completed.

In the accompanying drawings A represents the heater or steam generatorwhich comprises a closed hollow shell adapted to contain a quantity ofwater. One face a of the generatoris so shaped as to be clamped upon andto heat the'article to be vulcanized. The opposite face a is preferablyprovided with a series of hollow projections a 'communicating on the.inside with the generating chamber and adapted to expose a large surfaceof the generator to the action vulcanizing operation is of'the heatedgases from the burner to enable the desired steam erator to be quicklyattained. The projections a may be of various pattern.

A projection a of the generator from its facea is also preferablyprovided to serve as a suitable place for the attachment of a steampressure gage B, and also by acting as a lateral support and guidetoassist in plate or cap 0 in position. The steam generator ispreferably cast in one piece with its steam chamber cored out.

pressure in the gen- The flue (plate or cap C is fitted closely to theouter e ges of the face a of the generator being held in place by screwsa passing through ears 0 on the flue plate and threaded into lugs Dprojecting from the generator A. The upper end of flue plate G has arecess 0 into which the projection a fits. The lower end of the flueplate and the generator have semitubular projections a c which whenunited form a tube having preferably a raised external thread 0 overwhich the upper end of the external burner tube is ted to be threaded tosecure the burner adalp to t e generator. The flue plate Chas at itsupper end a series of openings 0" through which the heated gases fromthe burner may escape from the flue.

,The burner comprises an external tube E and an internal-tube F betweenwhich is an annular space G which is preferably packed or filled withabsorbent material such as spon e or cotton waste to be saturated withliqui fuel such as alcohol or gasolene. A wire screen 9 is alsopreferably employed to hold the absorbent material in place.

' H' represents a cap having preferably a disk of rubber or cork itinside next to its head and threaded to engage the lower end of theexternal burner tube E. The cap is preferably provided with a series ofperforations h arranged spirally so as to be successively uncovered asthe cap H is unscrewed from the. burner tube, the object ofsaidperforations being to supply air in reg- I ulated quantity to the innerburner tube point from excessive air currents. A slide plate I having aperforation i is also preferably employed to assist in regulating the iheat to the generator. This slide is adapted to be introduced to agreater or. less extent through a slit I in the projection a to closethe flue opening above the burner.

In operation theheater or steam generator A is clamped upon the face ofthe article K to be vulcanized, by strapping it directly to an inflatedrubber tire on by means of a plate L to support the opposite face of thearticle K, to which the generator A is attached by bolts Z. when not inuse is tightly capped at the lower end by cap H, the disk h of whichwhen screwed home forms a tight joint with the bottom of the burner, anda cap N having a disk similar to disk '72,, which when screwed toplaceserves-to close the upper end of the burner, and to prevent theescape or loss of the fuel or danger from its becoming ignited. Afterremoving the cap N and partially or entirely unscrewing the cap H theburner is ignited at the face of the screen 9 and the burner tube Escrewed upon the end of the tube formed by projections e c". Air issupplied to support combustion through the inner burner tube F, and theamount thereof can be regulated by turning the cap H to expose a greateror less number of perforations. h below the lower end of the tube E. Atthe commence The burner ment of the vulcanizing operation air isliberally supplied to the lower end of tube F to secure a maximum flameand to quickly raise the generator to the desired temperature, which isindicated, say when the pressure age indicates a pressure of sixty fivepoun s, the supply of air at the lower end of tube F is then reduced andthe supply of air through the notches 0 regulated, and the slidg; Iinserted and adjusted so as to maintain a small flame at the burnersuffi- -cient to maintain a uniform gage pressure until the vulcanizi-ngoperation is completed, after which the flame is extinguished, theburner again detached and capped, and the heater A' detached from thearticle. The air supplied through the notches a? may with a large 'flameserve to support combustion, and with a small flame may serve to diluteand reduce the temperature of the products of combustion. A uniformheat" is secured over the entire face a of the generaton' The mechanismherein illustrated and 1 described is capable of considerablemodification without departing from the principle of my invention.
